Quickheal : Security Vulnerabilities, CVEs, CVSS score >= 8

Quick Heal Internet Security 10.1.0.316, Quick Heal Total Security 10.1.0.316, and Quick Heal AntiVirus Pro 10.1.0.316 are vulnerable to Memory Corruption while parsing a malformed Mach-O file.

Quick Heal Internet Security 10.1.0.316, Quick Heal Total Security 10.1.0.316, and Quick Heal AntiVirus Pro 10.1.0.316 are vulnerable to Memory Corruption while parsing a malformed Mach-O file.

Quick Heal Internet Security 10.1.0.316, Quick Heal Total Security 10.1.0.316, and Quick Heal AntiVirus Pro 10.1.0.316 are vulnerable to Out of Bounds Write on a Heap Buffer due to improper validation of dwCompressionSize of Microsoft WIM Header WIMHEADER_V1_PACKED. This vulnerability can be exploited to gain Remote Code Execution as well as Privilege Escalation.

Stack-based buffer overflow in Quick Heal Internet Security 10.1.0.316 and earlier, Total Security 10.1.0.316 and earlier, and AntiVirus Pro 10.1.0.316 and earlier on OS X allows remote attackers to execute arbitrary code via a crafted LC_UNIXTHREAD.cmdsize field in a Mach-O file that is mishandled during a Security Scan (aka Custom Scan) operation.

CAT-QuickHeal 10.00 and possibly 9.50, when Internet Explorer 6 or 7 is used, allows remote attackers to bypass detection of malware in an HTML document by placing an MZ header (aka "EXE info") at the beginning, and modifying the filename to have (1) no extension, (2) a .txt extension, or (3) a .jpg extension, as demonstrated by a document containing a CVE-2006-5745 exploit.
